Sending mail through your own mailserver, running on a &quot;home&quot;
connection, is more and more a unwelcome practice and many ISPs block
already traffic on port 25 (use submit instead). There are plenty of free
mail services and lots of pay-for mail services which are very good, if
your ISPs mail service does not fit you. There is no need to run your own
mail server, if you want/need to, get a static IP. Then its your problem
to get delisted from the DSBL.<br><br>
To answer/comment your points:<br>
1) How he knows?<br>
2) of course not. Why should it? What has your mail content with your IP
address to do?<br>
3) Most RBLs are wrong in one way or another. <br><br>
The main problem here is that almost all anti-spam solutions first check
the IP address and then the contents. Natural, given that the IP is the
first thing the mail server knows about the client.&nbsp;&nbsp; It is a
major problem to receive the whole mail, just to decide later on that the
mail is to be rejected because of a blacklisted IP. <br>
So if your IP is blacklisted (and often even static IPs from large
organizations get blacklisted) you are out. Point. Use a regular mail
service.<br><br>
